Trial overview
Official title: Protocol for evidence synthesis to assess comparative efficacy of triple therapies versus other combination treatments for COPD in adult patients
Trial description: Triple combination therapy is increasingly being used in COPD management. One such triple combination is Fluticasone furoate/Umeclidinium/Vilanterol (FF/UMEC/VI). But currently, FF/UMEC/VI has no direct evidence compared with other relevant triple therapy combinations. Therefore the aim of this retrospective study is to explain the evidence synthesis to assess comparative efficacy of triple therapies versus other combination treatments for COPD in adult subjects. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines will be used to identify published, randomized controlled clinical trials (RCTs) comparing selected therapies in subjects with COPD. A systematic literature review including these studies will be then used to perform a frequentist indirect treatment comparison and a Bayesian network meta-analysis.

- Only RCTs, irrespective of blinding status, Phase III or Phase IV, parallel-group with minimum study duration of 8 weeks.
- Studies reporting outcomes of interest for ICS/LABA + LAMA combination therapies compared to each other or to LAMA/LABA + placebo, LABA/ICS + placebo.
- For abstract selection: Cross-over studies, if cross over before 8 weeks in each arm, Post-hoc or retrospective analyses, Cost-effectiveness analyses, Observational studies, Reviews or meta-analyses, Methodology studies or protocols, N of 1 trials (sample size of 1 subject). Studies lasting less than 8 weeks. Studies which are not in English or German language. Studies with conference abstracts before 2009.
- For full-text selection: Studies where subjects were required to spend time in a sleep laboratory.
Inclusion and exclusion criteria
Inclusion criteria:
- Only RCTs, irrespective of blinding status, Phase III or Phase IV, parallel-group with minimum study duration of 8 weeks.
- Studies reporting outcomes of interest for ICS/LABA + LAMA combination therapies compared to each other or to LAMA/LABA + placebo, LABA/ICS + placebo.
- Subjects with COPD as defined by Global initiative for chronic Obstructive Lung Disease (GOLD) guidelines (i.e. airflow limitation that is not fully reversible).
- Studies that include asthma and COPD subjects and report data for COPD subjects separately.
- Studies that include adults and children and report data for adults separately.
- For Full text selection : Studies that report results for at least one of these outcomes at 8-16 weeks or 20-28 weeks (for all treatments): Trough FEV1, SGRQ, TDI, rescue medication use.
Exclusion criteria:
- For abstract selection: Cross-over studies, if cross over before 8 weeks in each arm, Post-hoc or retrospective analyses, Cost-effectiveness analyses, Observational studies, Reviews or meta-analyses, Methodology studies or protocols, N of 1 trials (sample size of 1 subject). Studies lasting less than 8 weeks. Studies which are not in English or German language. Studies with conference abstracts before 2009.
- For full-text selection: Studies where subjects were required to spend time in a sleep laboratory.
- Studies with following interventions: Beta-agonists (Bambuterol; Fonoterol; Tulobuterol), Short-acting anticholinergics (Ipratropium; Oxitropium), Methylxanthines (Theophylline), leukotriene receptor antagonists (montelukast), COPD drugs in development or targeting other pathways (roflumilast; polyvalent mechanical bacterial lysate; lipopolysaccharide), All other pharmaceutical interventions not treating COPD (enoxaparin sodium), Non-pharmaceutical interventions such as pulmonary rehabilitation.
- Studies that only compare treatments that are not of interest; studies that only include the treatments of interest in combination with treatments not of interest (i.e. prednisolone + formoterol); studies that only include the partial combinations of treatments of interest (i.e. tiotropium+ ICS).
- Studies with only healthy subjects without COPD; studies with subjects who have reversible airway or obstructive lung disease; studies with only subjects with asthma; studies that include asthma and COPD subjects but do not report data for COPD subjects separately; studies with only subjects who have alpha-1-antitrypsin-definciency-realted COPD; studies that include only children; studies that include adults and children but do not report data for adults separately.
- Trials in non-Caucasian population e.g. Chinese, Japanese subjects (including non-Caucasian registries).
- For full-text selection: Studies in which none of the relevant outcomes are reported. Studies which report only the following outcomes without any outcomes of interest: mortality; bioactivity outcomes or biomarkers of inflammation; lung mucociliary clearance; arterial blood gases or degree of pulmonary hyper-inflation; plethysmography and oscillometry; nocturnal hypoxemia; quality of life in EuroQol and Outcomes reported at other time points.
